Hi Lynn,
yes, have a look on this sites:
"Using Outlook, what is the limit to the number of addresses I can have in a
personal distribution list?"
http://kb.iu.edu/data/agvq.html
"Is there a limit on the size of a distribution list? "
http://www2.warwick.ac.uk/services/.../staffemail/faqs/project/distributionlistsize
and:
You receive a "This distribution list has reached the maximum size for your
network e-mail server" error message when you try to add many items to a
contact distribution list in Outlook:

Maybe it helps.
